What is ultrasound for hip dysplasia?
Ultrasound for hip dysplasia is a fast, safe, and noninvasive imaging technique that evaluates the muscles, tendons, ligaments, joints and bones of a child’s hip area using sound waves. Hip dysplasia is the term for a medical condition in which the hip socket doesn’t fully cover the ball portion of the upper thighbone, increasing the risk of hip dislocation. The condition is usually present at birth (congenital). Doctors will perform a hip examination on your baby at birth and during well-baby checks.
By using a special ultrasound transducer, this test can visualize internal body structures without exposing the child to ionizing radiation (X-rays). Ultrasound has no known harmful side effects, and it is a fast, non-invasive way for doctors to evaluate soft tissues that don’t show up on regular X-ray exams. This technique is especially useful to visualize the appearance, size, consistency, and shape of internal structures and abnormalities.
The ultrasound transducer sends out small pulses of high-frequency sound waves. When pressed against the skin, the transducer transmits the sound waves that bounce off structures in the body. The transducer picks up the rebounding sound waves, and, with the help of a computer, the characteristics of a structure can be determined.
Ultrasound is performed for babies up to 4 months of age when a doctor sees sign of hip dysplasia, such as hip stiffness or a difference in leg length. Symptoms are often noticed during the newborn health assessment or at a well-baby check.
To help the infant remain still for the ultrasound, be sure they are well fed and have small toys to distract them during the examination.
To schedule an ultrasound, please speak to your health care provider and call our scheduling team at (512) 453-6100 or toll free at (800) 998-8214. A health care provider referral is required to make an appointment.
A radiologist, a physician specifically trained to interpret radiological examinations, will analyze the images and send a signed report to the provider who referred you to ARA. The health care provider will then share the results with you. Your report will also be available on the patient portal within 3 business days.
ARA continues to follow CDC guidelines in requiring employees and patients to wear masks at our imaging centers for the safety of all.
